The zinc-magnesium coating consists of a special zinc-aluminium-magnesium mixture. The sum of aluminium and magnesium is between 1.5% and 8%, the remainder being zinc. The minimum magnesium content must be no less than 0.2 per cent. This technology guarantees significantly higher corrosion resistance compared to other types of coating.
It is particularly suitable for very aggressive environments, when a very high standard of corrosion resistance is required.

The category of coated structural steels allows users to have excellent performance in terms of strength, with a high minimum yield strength index.
In addition to these mechanical properties, the chosen coating allows protection from oxidation even after the material has been processed.
The higher the grade chosen, S220GD ==> S350GD, the greater the material’s propensity for mechanical resistance.
Also called micro-alloy steels, in addition to a low carbon content they have a high purity internal molecular structure. Due to their low carbon content, they exhibit improved weldability. The ductility, fatigue resistance and formability of these steels offer high performance at a low weight.
